The Lenovo ThinkPad T14s Gen6 provides external DisplayPort on all 2 USB Type-C ports. Each one of this ports is connected to a dedicated DisplayPort controller. Due to support missing in the USB/DisplayPort combo PHY driver, the external DisplayPort is limited to 2 lanes. So enable the first and second DisplayPort controllers and limit their data lanes number to 2.
